見積もりで、何を決定させたいか
(要約)
見積もりをする = 何を獲得したいのか、何を失うのかを問い続ける。
何も得るものがなければ、見積もりはいらない
大体、その多くは施策の実施判断と人的リソースの調整に使われる
For me, estimation is valuable when it helps you make a significant decision.
My first example of an estimation-informed decision is allocation of resources. Organizations have a mostly fixed amount of
money and people, and usually there are too many worthwhile things to do. So people are faced with decisions: do we do A or B?
Faced with such a decision it's useful to know how much effort (and cost) each will involve. To make sensible decisions about
what to do, you need to have a feel for both the cost and the benefits.
